Resistance hysteresis in twisted bilayer graphene: Intrinsic versus extrinsic effects
Ranit Dutta, Ayan Ghosh, Kenji Watanabe +2
Hysteresis in resistance under magnetic field sweeps is a key signature for identifying magnetism in twisted bilayer graphene and similar systems. However, such sweeps can induce e…

Thermopower probing emergent local moments in magic-angle twisted bilayer graphene
Ayan Ghosh, Souvik Chakraborty, Ranit Dutta +7
Recent experiments on magic-angle twisted bilayer graphene (MATBLG) have revealed the formation of flatbands, suggesting that correlation effects are likely to dominate in this sys…
